AbstractTo investigate the regulatory effects of mixed application of 3% diethyl aminoethyl hexanoate·27% ethephonand zincsulfate onsummer maize，Hanyu 398 was usedas the experimental material.5 fertlization treatments weresetup：FO（nofertilization），F1（conventionalcompoundfertilizer），F2（sulfur-coatedslow/controlled-release compound fertilizer），F3（urea-formaldehydeslow/controlld-releasecompoundfertilizer），andF4（polymer-coatedslow/ controlled-releasecompound fertilizer）.3spray treatments wereapplied：PO （spraying with clear water），P1 （spraying with 3% diethyl aminoethyl hexanoate·27% ethephon），and P2 （spraying with 3% diethyl aminoethyl hexanoate‘ 27% （20 ethephon + zinc sulfate）.The effects of each treatment on plant traits，ear traits，and yield of summer maize were analyzed.Theresultsshowedthat，acrossallfertilization treatments，compared withPO，Plreduced plantheight，ear height，100-kernel weight，and kernelnumber perearby3.0-14.6cm，3.0-12.3cm，2.5-15.0g，and3.1-59.5grains， respectively，while yield was reduced by1.5%-18.9%.In contrast，compared with P1，P2 increased plant height，ear height，1000-kernel weight，and kernel number perearby1.0-14.5cm，1.5-10.5cm，0.5-16.0g，and4.4-40.8 grains， respectively，while yield was increased by 1.2%-17.9% .In conclusion，it was demonstrated that the combined application of 3% diethyl aminoethyl hexanoate·27% ethephon and zinc sulfate could achieve better chemical control effectsinmaize cultivation.
